4.2.2. Supervisor Functions Descriptions [LF]

There are 8 functions.

LF 1

Calibration: see chapter 6. Calibration on page 17 for a detailed procedure.

LF 2

Configuration: use this item to configure system parameters, specific sections of the

operating modes. See chapter 5. Scale Configuration at page 16.

LF 3

Linearization: use this to add 1-3 linearization points for the scale equivalent to 0, 1/3,

2/3 and 3/3 of the max capacity.

CAUTION! Perform the linearity procedure only if test weights applied to the scale

between the zero and span calibration points are showing slight inaccuracies, such as ±

a few divisions. If large inaccuracies are recorded, this indicates a possible mechanical

problem or possible load cell failure which linearity calibration may not be able to correct.

LF 4

ADC Update Rate: use this to select the sampling frequency: 15 (1), 30 (2) or 7.5Hz (3)

Factory default: SPEEd 1 (standard 15Hz)

LF 5

Zero Tracking: use this to define a ± 0 /5 divisions range around zero. When scale

weight is not at the center of zero but inside this range, ½ of the weight will be subtracted

until that the weight is inside the center of zero region.

Factory default: ZP 0 (off)

LF 6

Factory default: none

LF 7

Gravitational value: use this item to key in a G constant value: 9.78031 < G < 9.83217

If the scale has been calibrated at a different location and it is not possible to re-calibrate

with known test weights, the scale can be adjusted using this gravity factor.

Factory default: 9.81259

LF 8

Zeroing at Every Power UP: use this items to set an auto zero at the power up.

Factory default: SEtZ Y (on)
